Adding an edge to a knit scarf gives the perfect amount of detail and creates a finished look. Whether the scarf is knit with needles or on a loom, it is impossible to add an edge once the project is complete. Using the same yarn as the scarf, or a contrasting color, add a simple but beautiful crocheted edge into the knit stitches of the scarf.
Choose a crochet hook to add the edging to the knit scarf. The width of the hook should be approximately the same size as the knitting needles. This will ensure that the size of the crocheted stitches will be the same as the knitted stitches.
Tie a slip knot at the end of the strand of yarn. Insert the shaft of the crochet hook into the slip knot and pull it tight, securing it onto the hook.
Stick the crochet hook into the left corner stitch on one short end of the scarf. Crochet a slip stitch to join the yarn with the knitted stitch of the scarf.
Create a double crochet in the same joined stitch to begin the first cluster on the edge. Chain three and create a triple crochet, still in the same joined stitch to finish the cluster.
Work along the end of the scarf, creating a cluster in each stitch. This creates a ridged look to the end of the scarf. Chain one after the last cluster is made in the right corner. Chain one and turn to work along the bottom of the scarf.
Create a single crochet in each knitted stitch along the bottom edge of the scarf. This creates a lined look along the edge. Chain one when you reach the end of the scarf.
Turn and create clusters along the end of the knitted scarf, matching the other end. Create a double crochet in the first knitted stitch on the end. Chain three and create a triple crochet in the same stitch, creating the cluster.
Crochet a cluster in each knitted stitch at the end of the scarf. Chain one and turn to work along the top of the scarf, back to the beginning.
Crochet along the top, making a single crochet in each stitch, identical to the bottom. Chain one when you reach the starting point of the edging.
Join the end to the beginning with a slip stitch. Tie off and cut the yarn, leaving a short tail.
Weave the yarn tail into the stitches of the scarf, concealing it from view.
